Poland: Saint Mary's Cathedral in Kraków with Postcrossing Postmark

On Tuesday I got two postcards: one from Poland and one from Lithuania.

The card from Poland shows the Saint Mary's Cathedral in Kraków. The Saint Mary's Cathedral is a Catholic church on Kraków's main market square. It was built in the 14th century and is considered to be one of the best examples of Polish Gothic architecture. As part of the Historic Centre of Kraków is the church since 1978 on the UNESCO World Heritage List.

The card was signed during the recent Postcrossing meet-up in Kraków.
Stamp:
